Well thought out. There's a lot of changes between 3.4 and 4.4, and thet's probably part of the reason people haven't been responding in droves -- it would be hard to sit down and figure out every last thing that moved and how or why it might break any one of the many software packages you're asking about. > > 1. what's going to happen to the existing installations of : > > > > Apache/PHP > > MySQL > > Samba > > NATD > > IPFW > > Perl Perl will get upgraded. The rest of those can be backed up pretty easily. A mysql-dump, a few config files, some html... but you will have some trouble if you try saving the binaries. Apache probably will be missing a library or two, and would be happier with a rebuild. This I know from my own experience. > > I'm hoping that they will be effectively untouched (with the possible > > exception of IPFW - see question 2) is that correct ? The config files will all work with new binaries. And why not upgrade the binaries, since you are bothing to upgrade the OS and all? > > 2.

What's going to happen to users/groups etc ? Those files are listed on the 'upgrade' page, so I imagine they'll be right where you expect them. > > 4. Are config files such as inetd.conf going to get overwritten ? Again, that's on the upgrade page. My opinion is that you should back up everything you're attached to, wipe the box, and build it clean from the ground up. You may not be able to do that, as it may be a production server that is in constant need, in which case you probably shouldn't be upgrading it. Good luck, anyhow. I hope my answer at least helped a little. Thomas To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
